Abstract:
[ABSTRACT]OBJECTIVETo investigate the therapeutic effect of early combination treatment with intratympanic glucocorticoid injection for sudden sensorineural hearing loss(SSNHL).METHODSTotal of 178 patients with diagnosis of SSNHL, including 44 with hearing loss at middle-low frequencies,50 at high frequencies,44 at all frequencies and 40 at total deafness, were randomly divided into combination treatment group (CT group) and systemic oral prednisone group (OP group).CT group (82 patients) received intratympanic administration of methylprednisolone and oral prednisone in tapering doses. Pure-tone threshold audiometry (PTA) was performed at week 8 after beginning of therapy. RESULTSIn middle-low frequencies, the final PTA and PTA improvement were 26.14±24.82 dB and 42.23±1.61 dB in CT group respectively, and were 37.91±13.98 dB and 30.00±13.30 dB in OP group respectively (both P<0.05). In high frequencies, all frequencies and total deafness SSNHL group, the differences of the final PTA and PTA improvement were not statistically significant in both groups. The PTA improvement in CT group for total deafness (26.52±14.03) dB was more than that of OP group (22.06±11.17)dB (t=2.361,P<0.05). In middle-low frequencies, the recovery rate was 72.73%(16 cases) in CT group, and 40.91% (9 cases) in OP group, the difference was significant (χ2=4.539,P<0.05), but not in apparent effective rate, effective rate and total effective rate. In high frequencies, all frequencies and total deafness, there were no significant differences in therapeutic effect. The recovery rate of total CT group (40.24%) was significantly increased compared with that of OP group (26.04%)(χ2=4.061,P<0.05), the differences of apparent effective rate, effective rate and total effective rate were not statistically significant in both groups.CONCLUSIONFor low-middle frequencies SSNHL, the early combination treatment with intratympanic glucocorticoid injection leads to higher hearing recovery and therapeutic effect compared with traditional oral prednisone. Systemic application should be applied for high frequencies, all frequencies and total deafness of SSNHL.
